To calculate the value of each portion of your data we took each companies
ARPU (Average Revenue Per User). This is a good approximate metric, though it is
most certainly approximate. Where an exact ARPU is not available, an approximation based on industry is used.
Also, much of the value of the Datum Network comes from
the fact that data can be examined in context. This means that Facebook data
can be examined alongside Soundcloud and Stumbleupon data, adding invaluable cross-over
and the broader picture of the digital you (anonymous or not, this of course is your choice).
To account for this, the more data sources that are selected, the more each is worth.
we multiply the value found from the ARPU by (1+.1n), so all your data gets slightly
more valuable the more you share.
